Operation
commands
After
writing
the
axis
assignment
data
to
COMB1
(address
1
when
a
Z80
I/F
is
used),
write
the
command
to
COMB0
(address
0
when
a
Z80
I/F
is
used),
the
LSI
will
start
and
stop,
as
well
as
change
the
speed
of
the
output
pulses.
When
an
8086,
H8,
or

I/F
is
used,
write
16-bit
data,
which
combines
the

Procedure
for
writing
an
operation
command
(the
axis
assignment
is
omitted)
Write
a
command
to
COMB0
(address
0
when
a
Z80
I/F
is
used).
A
waiting
time
of
4
register
reference
clock
cycles
(approximately
0.2
μsec
when
CLK
=
19.6608
MHz)
is
required
for
the
interval
between
"writing
a
command"
and
"writing
the
next
command,"
"writing
a
register"
and
"writing
the
I/O
buffer,"
and
between
"reading
a
register"
and
"reading
the
I/O
buffer."
When
the
WRQ
output
signal
is
used
by
connecting
it
to
the
CPU,
the
CPU
automatically
ensures
this
waiting
time.
If
you
want
to
use
a
CPU
that
does
not
have
this
waiting
function,
arrange
the
program
sequence
so
that
access
is
only
allowed
after
confirming
that
the
IFB
output
signal
is
HIGH.
